Hi everybody, my problem is connected with the new OCR. I am studying old historic books for certain features. E.g. by Franz Xaver Schweickhardt (https://de.wikipedia.org/wiki/Franz_Xaver_Schweickhardt with the MANY volumes of his description of Lower Austria. Years ago it was possible to search in these books, nowadays this is not possible any longer. Can anybody help? This would increase my possibilities to a great extent! Best regards Otto

Hi Jeff and thanks for help! One of the many links to this series of books is: https://archive.org/details/darstellungdese06schwgoog/page/n235/mode/2up?q=Erdst%C3%A4llen
I am looking for expressions like "Erdstall" of Erdställe", which definitely is written on page 227, but is not found by OCR.

Hi Jeff, the problem seems to be difficult. But it would be a really great help if OCR would work (it is nearly impossible to read 36 volumes carefully)!! Could you think of another solution (maybe I can download the PDF-files and try myself?)? Best regards Otto

Hi Jeff, this problem seems to be difficult! On the other hand it is nearly impossible to read some 36 thick volumes carefully in search of a certain word... So it would be a great help indeed if OCR works!! Or can you think of other solutions (e.g. can I download the whole PDF files and try myself?)? Best regards Otto

you can search the FULL TEXT file https://archive.org/stream/darstellungdese06schwgoog/darstellungdese06schwgoog_djvu.txt

i found one instance of that name in it:
"In neuerer Zeit ftößt man bei Bearbeitung des Feldes öfter auf ſolche Erdſtälle."

Thank you for the hint! The problem is, that not all volumes offer FULL TEXT. And when you e.g. compare the original text with the full text of vol. 3 in the List of Wikipedia "Schweickhardt", you will see, that the OCR, which produced the full text, did not work well at all. So search is biased as well. Of course the scan quality of certain pages is low, but over all it is a matter of OCR quality (both FULL TEXT and search). This is a real pity! If there is any solid solution, please help!

FullText is missing: Bd. 2: https://archive.org/details/darstellungdese25schwgoog

Bd. 4: https://books.google.at/books?id=e54r-t9LPf8C&redir_esc=y&hl=de

But please compare the original with the full text (beginning of Bd 1,) :

Unfortunately I cannot include a jpg (mail does not work).
As you can see this FULL TEXT does not help at all, as hardly any word is spelled correctly and therefor cannot be located by search!
